"No, it won't have any effect if you don't switch gears after turning OD off/on or switching between power/normal modes. IE if you're set to normal/OD on while driving, then want to change to power/OD off, you'd need to switch into neutral, then push the power and OD buttons, then switch back to drive for the changes to activate. "

I took this off of of the Lexussc400.com forum.... is it true?

 

this isn't an suv... I hope we don't have to put it to neutral... what a burn......

 

Nope, when you release/press the button, the ecu will send the tranny the new instructions (power/od) right away and then the tranny will adapt right away... (Unless its in the middle of a shift.. then it will wait until its done...)

 

Thats what I thought, thanks

 

Oh boy, Sc4oo is right, sounds like the transfer case in a 4x4, whoever posted those instructions is a knucklehead......

 

You can answer that question yourself by trying it out on your SC. I can feel the overdrive difference in under a second, and the ECT difference on my next shift. Shifting to neutral, then pressing OD, then shifting back into drive will eventually kill your torque convertor. Imagine climbing a steep freeway grade at 5000rpm, switching to neutral while your tach drops to 1000rpm, then re-engaging the TC forcing it to neutralize the 4000rpm difference :eek:.

 

I think the web page was reffering to a SC400 w/ the 4WD option.

 

Hehe...
